[Studies on the levels of pO2 and pCO2 in the uterine cavity and uterine tissue (author's transl)].
The values of pO2 and pCO2 were determined in the uterine cavity by a medical mass spectrometer (MEDSPECT-MS80) in 45 cases of uterine myoma, 26 cervical carcinoma, 6 endometrial carcinoma and 20 normal uterus cases. The uterine tissue pO2 and pCO2 correlated with the pO2 and pCO2 determined in the uterine cavity or cervical canal. No statistically significant change of pO2 nor pCO2 was noted between the values of uterine cavity and cervical canal. The pO2 was higher and pCO2 was lower in the luteal phase than proliferative in 7 menstrual cycles. The mean values of intracavitary pO2 and pCO2 were 22.5 +/- 5.3 mmHg, 53.5 +/- 5.1 mmHg respectively in the cases of uterine myoma, 23.6 +/- 5.6 mmHg, 60.7 +/- 7.6 mmHg in cervical carcinoma, 20.8 +/- 1.0 mmHg, 54.5 +/- 3.7 mmHg in endometrial carcinoma and 28.5 +/- 4.3 mmHg, 53.5 +/- 5.1 mmHg in normal control uterus respectively. The intracavitary pO2 was lower and pCO2 was higher in the cases of uterine neoplasm than the control, and particularly the pCO2 was significantly higher in cervical carcinoma than the control.
